Quick question. I know when running gh to do 100mcg t4 ed with it and that is what I've been doing with 4iu ed. Thinking of switching to 10iu pwo 3x a week and I'm curious if you would still take the t4 daily, or only on those 3days, or not at all?
The T4 does not change at all. Once you started using exogenous T4 your bodies own production was shut down so GH dose, when you take GH, whether on GH or not, etc; doesn't even matter anymore. You are now on exogenous T4 and that controls your metabolic functions so the inhibition from somastatin rise while on GH at the thyroid gland is irrelevant at that point.
Yes run it as is brother. You can taper off slowly over a couple of weeks, or you can keep running the T4 that's really up to you.
Tapering off is not "necessary" to come off but it may help if you slowly drop to a really low dose so that your body would begin to produce it's own T4 again. Stopping cold turkey also seems to work just as well too.
